Answer:
Let P = Perimeter of square
Let l = Length of the sides of the square
P = 4l
Answer:
A;3600 yd2
Step-by-step explanation:
The surface area is found by adding the area of the sides
The area of the bottom is
A= s^2 where s is the side length since it is a square
A = s^2 = 30^2= 900
We can find the area of one of the sides and multiply by 4 since all the sides are the same
The sides are triangles so
A = 1/2 bh where b is the base b=30 and h is the height = 45
A = 1/2 (30)* 45
A = 675
We have 4 of these triangles
4*675 =2700
Add the 4 triangles and the bottom
2700+900
3600

I am joyous to assist you.
You can calculate polygon area with only apothem OR side length.
apothem only
area = apothem^2 * 6 * tan (180/6)
area = 10.4^2 * 6 * 0.57735
area = 108.16 *
<span>
<span>
<span>
3.4641
</span>
</span>
</span>
area =
<span>
<span>
<span>
374.677056
</span>
</span>
</span>
square yards
side length only
area = 6 * 12^2 * / 4*tan(30)
area = 864 / 4 * 0.57735
area = 864 /
<span>
<span>
<span>
2.3094
</span>
</span>
</span>
area =
<span>
<span>
<span>
374.1231488698
</span>
</span>
</span>
square yards
If apothem and side length were given with more precision, the answers would be closer.
